# How do you sketch the graph of a function?

Steps for Sketching the Graph of the Function
1. Determine, whether function is obtained by transforming a simpler function, and perform necessary steps for this simpler function.
2. Determine, whether function is even, odd or periodic.
3. Find y-intercept (point ).
4. Find x-intercepts (points where ).
5. Find what asymptotes does function have, if any.

Likewise, how do you graph different functions?

Here are some of the most commonly used functions, and their graphs:

1. Linear Function: f(x) = mx + b.
2. Square Function: f(x) = x2
3. Cube Function: f(x) = x3
4. Square Root Function: f(x) = √x.
5. Absolute Value Function: f(x) = |x|
6. Reciprocal Function. f(x) = 1/x.

Subsequently, question is, how do you graph a limit that does not exist? Here are the rules:

1. If the graph has a gap at the x value c, then the two-sided limit at that point will not exist.
2. If the graph has a vertical asymptote and one side of the asymptote goes toward infinity and the other goes toward negative infinity, then the limit does not exist.

Secondly, how do you graph restrictions?

To limit the domain or range (x or y values of a graph), you can add the restriction to the end of your equation in curly brackets {}. For example, y=2x{1<x<3} would graph the line y=2x for x values between 1 and 3. You can also use restrictions on the range of a function and any defined parameter.

How do you solve limits?

Find the limit by finding the lowest common denominator

1. Find the LCD of the fractions on the top.
2. Distribute the numerators on the top.
3. Add or subtract the numerators and then cancel terms.
4. Use the rules for fractions to simplify further.
5. Substitute the limit value into this function and simplify.
